Part D: Determination of the formula of a hydrate. Determine the mass of Water in the hydrate: _____ 2. Observing our nitrate, it has a white crystalline structure, representing that similar to table salt. Its formula is CuSO4 5H2O. They are known as “hydrated salts”, or simply, hydrates. The class average for the percentage of water in the hydrated copper (II) sulfate compound was 28.79%. Overview. The ratio of water molecules to the anhydrous salt is constant. View Lab Report-Determinining Formula of Hydrate.201930 (5).docx from CHEM 1411 at Collin College. Using crucible tongs, clean a porcelain crucible and its cover using concentrated nitric acid (6 M). x H 2 O, will be studied. Determining the Formula of a Hydrate. TIP: Click this link to fix system errors and boost system speed Copper (II) sulfate pentahydrate is an example of such a hydrate. Tetraamminecopper(II) Sulfate Monohydrate Cu(NH3)4SO4 • H2O bulk & research qty manufacturer. These compounds are called hydrates. In this section we will determine the number of moles of water present per mole of anhydrous solid in a given hydrate. Testable Prediction: Our unknown hydrate may be a hydrate of copper(II) sulfate, magnesium sulfate, iron(III) chloride, or iron(III) nitrate. We were trying to determine the mass of the hydrate, anhydrous salt, and water, as well as the empirical formulas for Copper (II) Sulfate (CuSO4). Many compounds exist as hydrates. 14457-55-7. Name: _ Patel Maitrykumari Determining Chemical Formula of Hydrate Pre-Lab Questions: 1.What is the Lab - Determining the Chemical Formula of a Hydrate Some ionic compounds form crystalline structures that trap water molecules within the crystalline framework. Pour the … A hydrate is an ionic compound that has a definite amount of water molecules attached to its crystalline structure. Hydrate Lab. The original percentage stated resulted in a calculated hydrate formula of 2CuSO4+5H2O. 1. while heating the hydrate so as to remove all water content, it is possible that complete heating did not take place and the student stopped heating before complete removal of water. 2 Determining the formula of a hydrate lab. Determine the number of moles of H20 in the hydrate: _____ (Hint: First determine GFM then use mole calculation in Table T of reference table) 4. 1. Experimental Question: How can we experimentally determine the formula of an unknown hydrate, A? A wide variety of hydrate formula options are available to you, such as sulphate, sulfide, and chemical auxiliary agent. Now it's time for data analysis. Chemistry I—Lab: Determining the Chemical Formula of a Hydrate. The five in front of the water formula show that 5 water molecules (or 5 moles of water per mole of CuSO4) are present per unit of the CuSO4 formula. Kimberly Graziano & Hyunjae Kim. Their formulas are written in two This lab activity combines in-class problem-solving with lab work. We want to determine the formula for a hydrate of iron (III) chloride, FeCl 3 nH 2 O. Here we are in the lab after dehydrating some iron (III) chloride salts. The lab work has two objectives: first, confirm the formula of a hydrate with known formula and second, find the formula of a hydrate in which the salt formula is known but not the molar amount of water. Determine the percent of water in the hydrate: _____ (Hint: Use percent compositon formula in Table T of reference table): 3. Purpose: The purpose of this lab is to ensure that the student understands the procedure of heating to constant mass and to determine from experimental data the number of moles of water released by a hydrate and infer the chemical formula of the hydrate. Purpose. Effect : this will cause decreased number of moles of water, thereby decreaing the water of crystallization present in the formula. The actual hydrate formula for the copper (II) sulfate compound was CuSO4+5H2O.
